-PALISADES PLANT -POWER INCREASE PLAN (TAC NO. 69344)

• By letter dated May 11, 1989, Consumers Power Company committed to notify the NRC at least two weeks prior to and receive NRC approval for any power increase above a nominal 80 percent power between May 2, 1989 and October 10, 1989. This submittal provides the two week notice and requests NRC approval to increase power to a nominal 90 percent in 5 percent increments.

Enclosed is the Power Increase Plan Criteria which will be used by the Palisades Plant during the power increase.

As has been previously discussed with the NRC staff, the increase in power will provide more data to evaluate power level dependency of the steam generator tube leakage. Consumers Power Company intends to implement the Power Increase Plan on September 13, 1989 and requests NRC approval by that date.
